Seriously is the iPhone4 battery life really that good ?

[Paulywauly]

I'm extremely happy with my iPhone 4 battery.

I get on average about 9 hours of usage out of mine before it dies, thats about 3/4 days for me. My old iPhone 3G needed charging alot more.

Post-Jailbreak Battery Life???

I want to JB also but just install BiteSMS and LockInfo. How is battery life after JB'ing? Is it the same as stock battery life? TIA

Do you clear your backgrounding bar at all? If you get sbsettings with a jb you can see how much memory(ram) is left in your phone. you typically get about 350 mb of ram when you turn it on. After you run a lot of apps and forget to clear the backgrounding dock thing it can get under 50mb. Clearing it up brings it close to, if not, 350 depending on your settings. So clear the dock regularly ( I do it after eveery few apps) and your battery life should improve. Also hard restart it like once every couple of days.

What am I doing wrong?

Fresh install of 4.3.3, not upgraded, not jailbroken, 16GB iPhone 4. 30 minutes fetch for two email accounts (Gmail and Y!Mail). CNN App push notifications. That's it- nothing else running in background.

*snip*

Not jailbroken, but I may as well as my heavily modded 32GB 4 gets around the same battery life. Going to restore both tonight and see if it changes.

Far from 'superior to any phone in the market right now' as some people seem to think...

I typically charge mine every night, but it usually has somewhere between 60-80% when I plug it in at night. That being said, I'm sure I could go a couple of days without it dying (in fact I have to do the occasional "heavy gaming session" to do a battery recalibration). As long as you have a chance to charge it daily you should be fine, even if you're a fairly heavy user. That being said: I've had it drop a good 10% an hour on standby if I'm in a really bad signal area. So, if you live or work in a dead zone, be careful about that.

I thought the same when i read that in a previous post.

 

[danpass]

Yeah but as your pic shows, it has been plugged in since the last full charge.

Anyone can get that if they plug it in every now and then.

What do you get off one single charge with out plugging in?

I plugged it in order to get a screenshot

Do you use the phone much then as I rarely get 6 hours out of a day???

 

[iEnvy]

From about 7am to 8pm, texting all day with a few calls here and there and moderate web usage, I get down to 20%

I'd like to see an Android device have this kind of battery life

How is that even possible?

 

[ajohnson253]

By far the iphone has the best battery I've used out of any phone I've used. Make the switch. Why not.

Fresh install of 4.3.3, not upgraded, not jailbroken, 16GB iPhone 4. 30 minutes fetch for two email accounts (Gmail and Y!Mail). CNN App push notifications. That's it- nothing else running in background.

With ~30 minutes of light web browsing (mostly forums and blogs), ~10 calls (each around 5 minutes), and looking at several emails, my phone dies at 6PM (off charger at 8am).

My 32GB isn't any better (although to be fair that thing is jailbroken and a crapton of mods and tweaks and background apps on it).

My Motorola Atrix 4G can easily go 2 days with the kind of usage detailed above.

Judging by the posts here I should be getting years out of my battery with that kind of usage. I guess I'll have to get a new battery or something

After the fresh install 4.3.3, did you set up as new phone or restore with back up?

Some of that usage probably can come from listening to music.
I listen to music on my phone overnight to help me fall asleep.
From 100% to 91%, I usually get 10 hours usage from the music. Another five hours of moderate usage, texting, occasional browsing, phone calls (on Edge), some more music takes me down to about 50%. Which is good for me. gets me through the day with enough juice to push through a second day.

Making telephone calls on Edge is the biggest difference, because I don't really notice any real reduction in call quality. On 3G it takes about 11 minutes to go down from 100% to 99, while on Edge it takes half an hour +.

Edit: To answer the topic at hand, yes... it is that good. If you actually use the "Phone" part, you will get at least two days of regular usage tops. Of course you aren't going to be getting the same usage if you're playing games and checking Facebook all of the time. (Just a general statement)

 

[nateo200]

YES!

Holy crap do you use your phone at all? Anyways my iPhone generally lasts from 5:30/6:30AM to 8:30PM at night where it is sitting at anywhere from 5-18%. Now if its a day like today where I'm taking photos, listening to music and uploading photos via cellular in a plays with pretty bad cell service then my battery will drain in about 8 hours if Im not toggling airplane mode.

TIMG that pic man. It's bloody enormous on my 11" air

My atrix is on its second day. Light-ish usage (nothing in background, cnn app push, gmail push, few texts, few calls) still have over 20%.

The battery life on this thing is astounding though and far surpasses anything I've had previously.

Tell me what you do to get that kinda battery life. My 4 on stock 4.3.3 dies within hours with fetch email and several push apps (news).

After the fresh install 4.3.3, did you set up as new phone or restore with back up?

Sorry should have elaborated- fresh install = [in my books] not upgraded, restored via DFU mode, nothing restored from previous phone, set up as new.

I like my phones to be nice and fresh after an upgrade

Maybe get it exchanged as that is definitely not normal at all.

Smartphones (that aren't ginormous) have crappy battery life, and if you are trying to run on a 4G network, unless your phone is the size of a laptop, the battery life is going to be totally unacceptable to most of us. That's why the iPhone probably won't be 4G in the next iteration either.

Personally, I find the iPhone 4 battery life pretty lousy, but make the tradeoff anyway. The thing is just so darned useful but I often find myself nursing the battery with my laptop or a charger when I am out during the day.

TIMGed it.

Nothing really. Fresh install, don't use push and 3G. Wifi is always on as is location services. Brightness at just over 50%.

I have since restored my 32GB iPhone and get slightly better battery life compared to my 16GB- neither are j/b'd, nothing in background, push Gmail, push CNN notifications, push Facebook notifications, and the usual assortment of texts (~50), email (~20) and calls (~10, 5 minutes each).

16GB gets approx 6 or so hours before dying, 32GB gets approx 10 [after fresh restore].

16GB is my work phone and my 32GB is my personal phone so yeah that's why I have two phones.

Going to restore my 16GB tomorrow and see if life increases. If not I'm going to buy a new OEM battery and swap that in and see if that helps.

I think each and every phone is different. My original iPhone 4 from release day had an awesome battery. Never got under 50%. But I dropped it and busted the screen and the replacement's battery is not nearly as good.

I hit 20% at least once a week now.

I hit 20% everyday!

... if you are trying to run on a 4G network, unless your phone is the size of a laptop, the battery life is going to be totally unacceptable to most of us.

Is that based on technical information/articles or is it extrapolating from the fact that 3G uses more power than 2G to give the assumption that 4G will use even more power than 3G?

I'm not trying to pick a fight or say your statement is wrong. I've been wondering for a while what 4G will do to battery life and your post seems to contain a reasonable quote to pick up on with a good chance that you (or others) could point me towards some answers.

I keep my iPhone locked to 2G to extend battery life and also because, when I'm doing small data transfers such as using the "Articles" app to look up something in Wikipedia, I see almost no difference in how long it takes before the article displays using 2G vs 3G. For me 3G does download faster but there is often a significantly longer latency (initial delay) before the article starts loading so all in all no real difference in user experience (for me). As for syncing calendar and contacts that all happens in the background anyway and is tiny amounts of data so 2G is just fine.

My "usual" usage time is about 5.5 hrs.

It depends on how I've charged the phone. When my usage gets into the 4 hr range I plug the phone in that night and then power off (it'll power on if you plug it in when already off)

That seems to get it back up to 5.5-6 hrs usage and beyond.
